Moments later, the SUV crashed into the car near the Busch Boulevard exit. Authorities say the SUV burst into flames and the unidentified driver died at the scene.

"His (the driver's) body was badly burnt in the crash, so we're waiting on dental records to make a positive ID, and the medical examiner will do an autopsy," said Florida Highway Patrol spokeswoman Sgt. Kim Montes. Part of that autopsy is determining whether he or she was on any alcohol or drugs."

Family friends of the students said they were coming from a party when the crash happened.

The students were all members of the same fraternity. The fraternity is raising money on gofundme.com for the victim's families.

Over the weekend, friends held a vigil for the victims.

"We wanted to do something more personal," said fraternity brother Nabil Tahan. "This is the last place they took their last breaths, so for us, this is a very significant spot in our hearts."

The highway was closed for several hours and reopened around 7 a.m.

The accident remains under investigation.

Grief counselors will be at the University of South Florida in Tampa on Monday to speak with students.
